Introduction 

 

WAFER-5821 is designed for limited space applications. 

It supports the full functions of an AT-compatible industrial 
computer on a single board. The WAFER-5821 is 
equipped with a low-power consumption and high 
performance GXLV/GX1 processor on board. It also 
contains an SDRAM SODIMM socket that can support up 
to 128MB memory. 

The WAFER-5821 provides an Ethernet interface, 

socket for DiskOnChip, EIDE interface, one parallel port, 
two serial ports RS232, two USB ports, and a header PS/2 
keyboard/mouse interface. The built-in SVGA display 
controller. It offers the resolutions of CRT up to 1280 x 
1024 @ 256 colors. The Flash ROM contains both the 
system BIOS and the VGA BIOS.  Reprogramming the 
Flash ROM could do the modification, in case of 
necessary.
